/* Admin surface stylesheet (served at /static/css/admin.css, linked from
 * frontend/templates/admin.html via versioned_url).
 * Brand alignment: values mirror the public app's theme tokens
 * (frontend/static/css/styles/themes/_theme.css) so the admin
 * surface reads as the same product. JS lives in
 * frontend/static/js/admin.js. Light-only by design — no dark theme
 * here; deliberately kept OUT of the public app entrypoints
 * (main.css / dark-mode.css). */
